This "Casual" Lemon Yellow cup and saucer by Russell Wright was made by Iroquois China between 1947 and 1967. The Casual pattern is a solid color mid century design in a round coupe shape.
The yellow cup measures 3-3/4 inches in diameter and 2-1/2 inches tall. The matching saucer is 6-inches in diameter.
The backstamp reads "Iroquois Casual China by Russell Wright USA Q3."
The cup is slightly darker than the saucer, especially around the rim and on the handle. There are a couple of scratch marks that look like pencil lines and one of the cups is stained with what looks like water dripping down the side. (Please see the photos, these sound worse than they look!) These flaws are reflected in the price.
There are two extra saucers that will be included at no charge with the purchase of both sets.
